Impact of the Circulating Current Control on Transient Submodule Voltage Stresses for Grid-Tied Modular Multilevel Converters During Grid Faults
TL;DR: A mathematical approach based on a typical MMC control strategy to investigate the interaction between the SM voltage and the circulating current suppression control is proposed and the time domain expression of the transient SM voltage during grid faults is derived.

Ariya Sangwongwanich,Yanfeng Shen,Andrii Chub,Elizaveta Liivik,Dmitri Vinnikov,Huai Wang,Frede Blaabjerg +6 more
TL;DR: An experimental-based reliability assessment is carried out using a two-stage micro-inverter where 60-cell and 72-cell PV modules are considered, and it is indicated that employing a 60- cell PV module is more beneficial for the micro- inverter, especially during a clear day.
